This invention relatesto an improved window chair, and important objects and advantages thereof are to provide a Window chair of the character described, which Will facilitate and expedite the cleaning and the making of repair to the outer Side of windows and eliminate all hazards ordinarily involved in such operations, which is adjustable to adapt same for use in connection with window sills of varying dimensions, and which may be compactly folded to facilitate the transportation and storage thereof.

Further objects ofthe invention are to provide a device of the class stated, which may be readily and conveniently engaged on a window sill or removed from the latter, which is simple in its construction and arrangement, durable and efficient in its use, and comparatively economical in its manufacture.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts herein'speciflcally described and illustrated in the accompanying drawing, but it is tobe understood that changes in the form, proportions and details of construction may be resorted to that come within the scope of the claims hereunto appended.

In the drawing wherein like numerals of reference designate corresponding parts throughout the several views:

Figure 1 is a front elevational View of the improved window chair in the erected position and constructed in accordance with the invention.

Figure 2 is a side elevational view thereof.

Figure 3 is a bottom plan view of the seat embodied in the invention.

Referring in detail to the drawing, the improved window chair comprises a rectangularly-shaped seat I, and a back 2 which has its lower end pivotally connected to the rear end of the seat by means of a pair of hinges 3.

The seat I and back 2 are preferably constructed of plywood to provide a light-weight and strong chair structure, but it will be obvious that the chair may be constructed of any other suitable material to best meet conditions found in practice.

The back 2 is reenforced by a pair of side rails 4 and by a cross rail 5, which rails are fixed in position on the rear face of the back. The side rails extend along the respective side edge margins of the back, and the cross rail extends along the lower edge margin of the back.

The seat I is reenforced by a pair of metal side straps 6, which are disposed on the top of the 1 Claim. (CILv 304-24) seat and extend along the side edge margins of the latter, and are permanently fixed in position by means of rivets 'I. The forward end of each of the side straps is formed into a downwardly disposed hook 8 which is adapted to overlap and engage the inner ledge of a'window sill 9 as clearly shown in vligure 2. Each of the hooks may be formed with a concaved free end I0 to augment its gripping action and thereby prevent the lateral slippage of the hook from its engaged position on the window sills. The inner surface of each of the hooks is preferably provided with a suitable lining II to prevent marring of the window sill by'the engagement ofthe hook with the latter. For the same reason, a cushioning strip I2, constructed of felt, rubber, or the like, is secured to and extends along the under face of the seat adjacent to the forward end of the latter.

lA cross bar I3, formed with a forwardly disposed depending flange I4, is adjustably mounted against the under face of the seat I by means of a pair of eye-bolts I5, which are engaged in the seat and in the side straps 6 and extend through transversely disposed slots I6 provided adjacent to respective ends of the cross bar.

The cross bar I3 is disposed adjacent to but is spaced from the forward end of the seat I, and its allowed adjustment permits the ange 4III to be abutted against the rear edge of the inner high ledge of the sill 9. Such abutment of the flange I4 prevents the disengagement of the hooks 8 from their engaged attachment on the sill, and further prevents the movement of the seat in either the forward or rearward direction on the sill; A

A comparatively wide cross member I1 is disposed against the underside of the seat I and extends along the rearward end of the latter. A pair of transversely extending seating blocks I8 are secured at respective ends of the cross member. The cross member I1, with the seating blocks I8, is adjustably attached to the seat I by a pair ofbolts I9, which latter are engaged in the side straps 6 and in the seat, and which extend through elongated slots 20 formed in the cross member and in the seating blocks.

The seating blocks I8 are adapted to rest upon thc outer low ledge of the sill 9, and are of such height that when the forward end of the seat I. with the cushioning strip I2, rests upon the inner high ledge of the sill, the seat I will be disposed on a level plane.

While the cross bar I3 and cross member I'I are adjustable in either the forward or rearward direction on the seat I to accommodate the device 3 to the window sill to which it is to be attached, it will here be noted that such adjustment usually need be made but once, as the window'sills of any particular building are generally of a uniform construction. When the device is once adjusted to suit the sill, no further adjustments are required to eiect the attachment of the device to the sil1 or its removal from the latter,

As the cross member I8 and seating blocks I8 sustain the load ;of the user seated in the device, the said elements are of a strong construction and allow the use of relatively light weight material in the construction of the associated seat I.

A pair of eye bolts 2I are secured in the back 2 adjacent to the upper ends of respective side rails 4. A pair of flexible members 22 are provided for holding the back 2 in the erected operative position, which is at a slight angle rearward from the vertical, as shown in Figure 2. One ,end of each of the flexible members 22 is secured to respective eye bolts 2l in thebaek-L `and the other ure 2.

'Vlhe present invention provides a most durable and efficient device of its kind, which may be economically constructed and conveniently and successfully employed for thepurposes and in the manner herein'set forth.

What I claim is:

A window chair .comprising the .combination of a seat, Va 'bach having la. hinged connection with said sea-t, a pair of side rails secured along the rear of respective side edges of said back, a pair of reye bolts secure in said back and in the upper ends of respective side rails. a cross rail secured against Ythe rear lower end of saidV back for reenforcing said hinged connection, a pair of reenforcing side straps secured along to top of respective side edge margins of said seat and having the forward end portions thereof formed to provide a pair of depending attaching hooks, a cushioning strip secured along the forward end of the underace of said seat, a pair of eye bolts engaged in said seat and in respective side straps, a cross bar including a forwardly disposed depending iiange adjustably connected against the under face of said seat adjacent to said cushioning strip by said eye bolts, each end of said cross bar being provided with a transversely disposed slot for receiving respective eye bolts and to allow the adjustment of said cross bar on said seat, a cross member extending along the under face of the rearward end of said seat, a pair of transversely extending seating blocks fixed at respective ends of said cross member and depending from the latter a. distance beyond the lower free edge of said flange, each end of said cross member and the seating block carried thereby being provided with a slot, a pair of bolts engaged in respective side straps and in respective last-mentioned slots for adjustably yconnecting said cross member to said seat, and a pair of flexible members secured to respective eye bolts in said seat and to respective eye bolts in said back for holding said back in the erected operative position.
